What Energy Rating Do Our Windows Hold?

In one of our earlier blogs we showed you How We Make our A-Rated units.
Now we're going to show you what ratings our uPVC windows carry. 

So firstly;

What is an energy rating? 

An Energy Rating is a rating of overall efficiency in the building. If you look at the image to the right of this text you will see an example of an Energy Rating Chart. It has a range of different levels from A-G. A being the most energy efficient and G being the least energy efficient 

U-Value

What is U-Value? U-Value measures the heat loss through your glass unit and is expressed in watts per kelvin meter square or W/KM². The lower the U-Value the better the insulation)

Our windows range from:
1.5 in our Double Glazed Units to 
0.6 in our Triple Glazed Units.

G-Value

What is G- Value? G-Value is the Solar Gain is the natural heat gain from the suns rays and it passes through your glass two ways;

(A) Directly through the glass {having Low E Extra Clear Glass allows easier passage for the natural light}

(B) Heat is also absorbed by the glass which is subsequently radiated inwards. 

The G-Value is the co-efficient that is used to measure this and ranges from 0-1.) 

Our G-Value in our Triple Glazed Unit is 0.55
and in our Double Glazed Unit is 0.74

Light Transmission

Light Transmission (the percentage of visible light transmitted through the glass) ranges from 0-100.

In our Triple Glazed Unit is 74%
in our Double Glazed unit is 75%

How to Choose your Glass:

The best combination is high thermal insulation, which means a low U Value combined with a G Value that is not too high and excellent optical clarity.

Our range of Glass as you can see tick all the boxes. The huge improvements that have been made through the advantages in glass and glazing components, allows us to bring this to you. Achieving U Value as low as 0.6 while retaining excellent light transmission in addition it is using natural light of the sun to your advantage. 

These advancements can reduce costs on your energy bills and create a comfortable living/ working environment for you. Harvest Energy use the latest designs in manufacturing,

all you have to do is enjoy the view, then enjoy your savings.
